Diversity and Distributions, Volume 27, Issue 9, Page 1696-1705, September 2021., 2021 Abstract Aim To understand spatial‐temporal changes (beta‐diversity) in coastal communities and their drivers in the context of climate change. Coastal ecosystems are extremely exposed and dynamic, where changes in seaweed assemblages have been associated with changing water temperatures. However, at local scale, the effects of changes in the upwelling

Drought, fire and grazing precursors to large‐scale pine forest decline
Diversity and Distributions, Volume 27, Issue 7, Page 1138-1151, July 2021., 2021 Abstract Aim Temperate forests are currently facing multiple stresses due to climate change, biological invasions, habitat fragmentation and fire regime change. How these stressors interact with each other influences how, when and whether ecosystems recover, or whether they adapt or transition to a different ecological state. Because forest recovery or

Climate change transforms the functional identity of Mediterranean coralligenous assemblages
Ecology Letters, Volume 24, Issue 5, Page 1038-1051, May 2021., 2021 Marine heatwaves (MHWs) are altering the structure of temperate coral‐dominated communities worlwide. Yet, the long‐term consequences for ecosystem functioning remain mostly uknown. Here, we quantified changes in functional structure of Mediterranean coralligenous assemblages by conducting a mulit‐taxa, trait‐based analysis.

Atividade biológica de metabólitos secundários de algas marinhas do gênero Laurencia [PDF]
Revista Brasileira de Farmacognosia, 2010 As algas vermelhas do genero Laurencia sao conhecidas como uma riquissima fonte de metabolitos secundarios. As principais classes quimicas ja isoladas sao terpenos - sesquiterpenos, diterpenos, triterpenos - e acetogeninas. Estudos apontam que estas substâncias apresentam importantes atividades biologicas, principalmente citotoxica e antibacteriana ...
